MURȂBAHAB LI AL-AMR BI AL-SHIRȂ’

CASTABILITY OF Al-Li-Mg AND Al-Li-Cu-Mg ALLOYS

The objective of the present work is to study the casting characteristics of various A1-Li alloys, which include fluidity and strengths of the alloys and their interaction with cast molds. Materials investigated are Al-Li-Mg and Al-Li-Cu-Mg alloys with Li content of 2.5 wt%. The results show that sand molds with resin binders are good for A1-Li casting. Ceramic coatings can further reduce the m...

Kitāb al-shukūk `alā Jālīnūs li-l-tabīb al-faylasūf Muhammad ibn Zakarīyā al-Rāzī

what is known as 'Arabian Medicine"' (p. VII). Recent research, however, shows more and more that one cannot speak of a medieval Jewish medicine proper. Jewish physicians studied the Arabic medical works which are based on the Galenic medical tradition. A good example is Maimonides, who according to Jewish scholars, made such a great contribution to medieval medicine. But it now clear that he w...

amr ibn bahr al- jahiz

like volter, french salient author, al- jahiz is a philosopher literate; namely, literary dimension of his personality predominates over his philosophical character. like other great literati and writer of the world, he was a master in all sciences and knowledge of his age including philosophy, speech, politics, and a verity of customs, beliefs and religions and in some of them he was skillful ...

THE ICOSAHEDRAL Al-Li-Cu PHASE

Zener Relaxation in Al-Li Binary Alloys

Internal friction (I.F.) and modulus measurements have been carried out as a function of temperature in order to study the Li mobility in an A1 8.1 at% Li 0.03 at% Zr alloy. The results show that the sequence of 6' and 6 precipitation can be followed through the evolution of the internal friction spectra. Two peaks appear in the internal friction spectrum. The low temperature peak Pz (450 K), h...
